AS OF LAST WEEK WHEN I DROPPED MINE OFF 1800+ were booked. They also have locked rooms for business record storage.

Nautique stored indoors at Marina with no climate control. Pontoon gets wrapped and stored in a boat years. Cigarette comes home with me and stays in my heated boat bay.

My method isn't very quick, but has yet to let me down. I have one of the west marine 5 gallon kits with a t valve. First thing I always do is stabil in the fuel. I run the motor on hose water for 10-15 minutes til motor is up to temp, once up to temp I'll switch my t valve to antifreeze and run till I see antifreeze out the exhaust. Once I see antifreeze coming out the exhaust I fog and kill the motor.
then I drain/suck engine and drive oil while it's still warm. Then pull block drain plugs and drain block completely. Change engine oil filter, fill engine and drive oil, fill block back up with antifreeze.
